WELLHEAD LEAK REPAIR
SEALMAKER formulations to quickly repair failed wellhead seals
Review case histories for Wellhead leak repairs
SEALMAKER sealants are formulated for wellhead leaks of all types, elostomeric, metal to metal, and all combinations therein. Wellhead leaks are common with the temperature and pressure variations combined with vibration and corossion, which amplifies the degradation of the seals, allowing pressures to communicate across the seals, and into the adjacent annuli. SEALMAKER's patented technology can not only restore the wellhead seals to regain well integrity, but they offer additional corossion protection by coating the internal components. The best benefit is that the void area is not compromised and full functionality of the wellhead remains allowing you to continue to test the voids normally. The ability to chemically repair wellhead leaks in a matter of hours and to be able to bring a well back on-line quickly saves you time and money eliminating the need to perform a major workover and in a fraction of the time.
The outstanding phyical properties of the resulting seal that is created gives you the confidence to know that the leak has been fixed and the system restored to full operational capability, as high as 20,000-psi and operating temperatures in excess of 700ºF. Our repairs have another unique property unlike any other. SEALMAKER has a strong fibrillating characteristic during activation within a leak path. This means that the final seal developed comprises of tighty intertwined fibrils which give it strength in all directions and that you will be able to pressure test your annulus in the opposite direction that the seal was set and not have to worry about it failing while it bonds tenaciuosly to the leak path walls. With SEALMAKER you mantain full functionality of the wellboreand do not have to develop special procedures after a repair has been made.
SEALMAKER is easy to apply in the field. The normal procedure is to provide our local personnel with the leak information known. We generally need the leak-rate, pressure information, normal operating pressures, annulus pressures, cavity volumes, pressure rating of the wellhead, stinger type utilized, and contact information and submit via our , from there you can also attach any associated files such as well-bore diagrams, diagnostics performed, etc., to help us generate a solution. We can then prepare a technical proposal including procedure, equipment list, and chemical list, and then issue a commercial proposal given the leak condition and upon approval begin the mobilization process. We have personnel, equipment, & chemicals stationed around the world to ensure a rapid repsonse time. Everything will then be mobilized to the job site and our highly experienced crews take over to apply the chemicals to the well and get it fixed. After treatment is complete and the leak has been sealed, the valve is typically cycled to ensure it is functioning properly, then the well is placed back on-line as quickly as possible and you are back on production, quickly, easily, and efficiently.
